Chapter 302: Fish I Undertook Pressure That I Shouldn't Have Bear (6.4K)

Ten minutes after the image was exposed.

The eel that Kirchhoff bought back had been disembowelled, its head drooping to the side, and a strange light shone in its eyes.

Riemann took the ring taken out of the belly of the fish and went to the faucet to wash it a few times.

After the blood and stains are cleaned.

Riemann pinched the ring with his index finger and thumb, put it in front of his eyebrows and looked at it, and said to Gauss:

"Teacher, this is a metal ring. It seems to be made of silver. There are words engraved on it."

Gauss glanced up at him, put down the water glass in his hand, and asked:

"What is written? Great Chuxing King Chen Sheng or the Supreme Lord of the Rings?"

Riemann looked at it for a while, and finally shook his head:

"The words are too vague to read clearly."

Gauss didn't pay much attention to this, but turned his head and asked Faraday:

"Michael, it really is a metal ring. By the way, how did you think that the ray could take such an image?"

Faraday exhaled a long breath with emotion on his face.

Then he pointed to the vacuum tubes lined up on the table, and said to Gauss:

"Friedrich, do you remember the various props we tried just now?"

Gauss was taken aback when he heard the words, but quickly replied:

"of course I remember."

Faraday stood up, signaled everyone to follow him to the console, pointed to the tried metal and said:

"You see, the steel plate is completely light-blocking, the wooden boards and books are completely light-transmitting, and the thin aluminum sheets are light-transmitting to a certain extent."

"So I was thinking about a question just now."

"Is there anything in the world that contains a small amount of metal and is mixed with other substances at the same time?"

"The answer is yes, that is."

As he spoke, he looked around, pointed to Gauss and the others with a smile, then pointed to the fish, and said:

"vertebrate!"

Gauss was silent for a moment, after a little thought, a word came out of his mouth:

"calcium?"

"bingo!"

Faraday snapped his fingers in a rare way, and it can be seen that the electrician is a little emotional at this time:

"It's calcium!"

Speaking of the substance calcium, many people subconsciously think of calcium carbonate.

It is the main component of limestone and marble.

On this basis, some people will regard calcium as stone foam, thus creating the illusion of non-metal.

But actually.

It is not difficult to see from the gold lettering it contains.

Calcium is not a non-metal, but a metallic element.

It is located in the 4th period and group IIA of the chemical element periodic table, and it is a silver-white crystal at room temperature.

One of the most abundant metal elements in the human body is calcium.

at the same time.

The discoverer of calcium is none other than Humphrey David who guided Faraday:

In May 1808.

David mixed wet quicklime and mercury oxide in a ratio of 3 to 1, placed it on a platinum sheet, and connected it to the positive electrode of the battery.

Then a depression was made in the mixture, mercury was poured in, a platinum wire was inserted, and it was connected with the negative electrode of the battery to obtain a relatively large amount of calcium amalgam.

Then he distilled the calcium amalgam to obtain silver-white metallic calcium.

And in the bones of the human body or vertebrates.

Calcium mainly exists in bones and teeth in the form of crystals, accounting for 1.5% to 2% of the total weight of the human body. It is an extremely abundant mineral in the human body.

So as David's second-in-command.

Faraday naturally thought of the concept of bones after he discovered that the mysterious rays had different penetration effects on different metals.

But mentioned earlier.

In the current timeline, the scientific community has a relatively deep understanding of the particle properties of light.

They know that the particle flow will carry a lot of energy, and the energy may affect the human body.

Just like raindrops, hail, and sandstorms in the macrocosm, it hurts when you hit your face.

Therefore, after thinking about it, Faraday chose the eel as the experimental subject.

Anyway, the eels don't mind, do they?

Then Faraday put the negative on the table, and seriously analyzed it with everyone:

"You can see that the cranial and pharyngeal cranial arches are very obvious, and the image of the lingual arch is relatively blurred."

"In addition, the spine and ribs are also very clear"

"This is the intermuscular bone under the fin, right? Such a small spine can be photographed clearly."

"Look at its mouth, it's round, deep and moist. If I pull out the teeth, I have a bold idea."

after awhile.

Gauss raised his head thoughtfully, looked around, and concluded:

"Based on the imaging results, the calcium in the bones seems to absorb the mysterious ray, while the internal organs are passed through by it."

"Thus, after the same intensity of light is injected, different image results will be presented on the film according to the distribution of bones and internal organs."

"As for whether other substances in the animal body will affect the mysterious rays, it is not known for the time being."

"Presumably with everyone's IQ, it shouldn't be difficult to understand the meaning of this situation, right?"

With the export of Gauss's words.

The atmosphere in the laboratory was suddenly quiet, and a needle could be heard in an instant.

Everyone here today has different backgrounds, either the stable version of the boss, or the youth version of the future boss.

So for them.

The deeper meaning of Gauss's words is not difficult to understand:

This ray can visualize fish, so naturally it is also applicable to the human body.

If conditions are right, transfer this ray from an eel to a human.

Well, at least in the field of medicine, there is the possibility of breakthroughs in many difficult and miscellaneous diseases!

For example, a fracture, a mass in the body, or wanting to get the bullet after being shot.

This is undoubtedly an epoch-making discovery for modern medicine.

In addition, its wavelength, frequency and other characteristics are bound to cause a big earthquake in physics!

Think here.

Weber, who was standing next to Gauss, couldn't help but feel a deep sense of gratitude while he was excited.

He was glad that he did not miss such an experiment today.

Today, whether it is the measurement of cathode rays, the calculation of the charge-to-mass ratio of particles composed of rays, or the discovery of unknown rays, any one of them has the status and value to be recorded in history.

Even if one is like this, let alone the gathering of the three.

It can be said like this.

One of these people at the scene today counts as one, and even the eel and the fish-selling fisherman will definitely be recorded in the history of physics.

In a way.

The achievement of everyone today is not to discover something, but to work together to open a door to a whole new world.

Even just looking at the light shining through the gate is enough to imagine the magnificence and vastness inside.

This moment.

Weber, a top electrician in the current world and even in the history of science, could not help but think of four words:

How lucky.

Weber couldn't help looking at Gauss, rolled up his sleeves, and said excitedly:

"Friedrich, since this is the case, let's try it with a human body, and I will be a volunteer!"

However, Gauss waved his hand at him and stopped him:

"Edward, don't worry, let me check something first."

After speaking, he turned around and came to the sink where the eels were placed.

It used to be a cleaning tank for chemical utensils, but now it is temporarily used as a shelter for eels.

After coming to the pool.

Gauss put on his gloves, picked up the knife that Riemann used to kill fish, and continued to dissect along the eel's abdomen.

After two or three minutes.

Looking at the scene in front of him, Gauss' breathing was slightly stagnant, and he waved to Faraday and others:

"Michael, come and have a look!"

Seeing this, Faraday put down the negatives, walked quickly to Gauss, and asked:

"What happened, Friedrich?"

Gauss took the cut eel to the platform of the sink, pointed at the edge of the knife and said:

"Look."

Faraday and others followed the trend.

Only at this moment.

On the belly of the eel that was cut open by Gauss, a small part of the meat that should have been pink and tender suddenly turned black!

Then Gauss picked up the fish with a knife, exposing the liver below.

Generally speaking.

An eel has a liver and a gallbladder in its body. The gallbladder can be used as medicine, but the liver is not recommended for consumption.

Fresh eel liver is navy blue, a transitional color between blue and black.

But at this moment.

More than one-third of the liver in front of Gauss and others has become

light yellow.

Then Faraday tried to touch it twice, and then tentatively said to Gauss:

"The protein and fat inside have gone bad?"

Gauss took off his gloves with a solemn expression, turned on the tap and washed his hands, and replied at the same time:

"That's right, if I'm not mistaken, that mysterious ray should be very destructive."

"If it is irradiated for too long, the fat and protein in the body are likely to undergo serious denaturation."

"Fortunately, we were not in a hurry. We took this eel up for a try first. If you and I played in person, I'm afraid the human body would suffer some irreversible damage."

It's a coincidence.

At this time, the eel's nerve cells were not completely dead, and suddenly it flapped its tail twice, which shocked everyone.

And in the corner that Gauss didn't notice, Xu Yun also nodded.

The concept of protein was already proposed by the Dutch scientist Gerrit in 1838. It is not surprising that Faraday knew the concept of denaturation.

And well known.

X-rays and ultraviolet rays have a lot of energy, and under long-term exposure, they can easily damage fats and proteins.

In Xu Yunlai's later life, some people liked to raise exotic animals.

For example, a red dragon centipede with a length of 20 centimeters, and a spider that is about the size of a palm, etc.

Even cockroaches such as Dubia and Cherry are raised.

There are also some people who like to raise ants, such as Yuan Yuan, Huang Qiong, Xiao Japan and so on.

One way to identify whether the queen is laying live eggs is to turn off the light and hold the ultraviolet light on the eggs for a few seconds.

The protein of the eggs is extremely sensitive to ultraviolet rays, and will soon produce wriggling, so that the activity of the eggs can be distinguished.

This is also one of the intuitive evidences of high-energy rays for protein properties.

And eel is a typical high-protein fish.

On average, every 100 grams of eel contains 18.6 grams of high-quality protein.

In addition, the liver of eel also contains a lot of fat - there is a health product called cod liver oil in later generations, which is a kind of fatty oil extracted from fish liver.

Although most of the fish used to extract cod liver oil in later generations are cod, there is also a lot of fat in eel liver.

Therefore, under the exposure of X-rays for up to fifteen minutes.

The fish bone of the eel was successfully imaged on the negative film, and the protein and liver of its main irradiation point were also denatured.

Then Gao paused, pointed to the negative not far away and said:

"According to the eel's situation, the exposure time of fifteen minutes is obviously too long-at least to apply this ray to the human body smoothly, we must reduce the exposure time of the film."

Faraday followed Gauss' gaze and looked at the film, and nodded in agreement:

"Indeed, the exposure time of 15 minutes is indeed a bit long, but the negatives of the rapid exposure seem to have not been released yet"

Speaking of which.

Faraday suddenly thought of something, blinked, and turned to look at Xu Yun.

"."

Xu Yun looked at him innocently, and asked with a cute face:

"What's the matter, Professor Faraday? o(*≧▽≦)ツ"

Faraday took a deep look at him and asked aloud:

"Student Luo Feng, I wonder if Mr. Fat Yu left any manuscripts related to negatives?"

As a result, before he finished speaking, Xu Yun interrupted him:

"Sorry, Professor Faraday, the ancestors did not leave any manuscripts about the negatives."

Faraday was still not reconciled, and continued to ask:

"Really? I can exchange Friedrich's manuscript with you!"

Gauss on the side: "??"

However, to Faraday's disappointment, Xu Yun still shook his head:

"No."

Then Xu Yun paused and explained:

"Professor Faraday, don't forget that the camera was invented in 1839."

"No matter how powerful the ancestor of Fat Fish is, he couldn't have studied negatives before the advent of cameras, do you think so?"

"This is not a problem of technology or ability, but a difference of the times, which is beyond the reach of human beings."

Faraday blinked quickly when he heard the words.

It seems to be the truth.

So he sighed with some regret, and a trace of loss flashed in his eyes.

Looking at Faraday, who was a little depressed, Xu Yun couldn't help opening his mouth, but he still didn't speak in the end.

After all, according to the normal historical trajectory.

Just one more year. That's 1851.

A videographer named Frederick Scott Archer would have invented the collodion wet plate photography method.

Its principle is to mix bromide, iodide and collodion diluted with ether and spread it evenly on the glass. The glass plate is immersed in silver nitrate solution to form a sensitive silver iodide photosensitive layer.

Then take it out of the silver nitrate, and complete the exposure quickly while the photosensitive layer of the collodion is still wet.

The speed of this exposure method only needs 15 seconds to half a minute, and it has been the leader in the photography industry for more than 30 years.

Of course.

Seeing this, some students may ask:

No wow, then why didn't Roentgen use this method?

The answer is simple.

Roentgen actually tried the wet plate photography method, but in the end the visualization was unsuccessful, so he could only continue to use the ancient daguerreotype method.

But what he didn't know was.

In fact, he only needs to remove the link of ether, and finally X-rays can be imaged on the film.

However, this step seems simple, but it has actually troubled the photography industry for fifty years.

Of course.

For Xu Yun who travels through later generations, this question is so simple that it couldn't be simpler.

Therefore, instead of doing something to attract attention at this time, it is better to follow the trend of history and wait for Archer's invention to appear.

At that time, as long as he pretends to accidentally add less ether, he can successfully resolve this barrier.

And at this time he

Just be a mascot.

After all, his presence in front of Faraday and others seems to be a bit high-profile now-although a large part of it is due to Mai's two ahs.

But Faraday didn't know the future direction, so he could only sigh faintly:

"Hey, negatives"

He never expected.

At this point, the exposure problem of negatives will actually become a stumbling block in front of us.

However, scientific research is often like this.

Accuracy problems often become shackles that restrain you from moving forward.

As it was in 1850, so it will be in 2022—and the latter will be even crueler.

In fact, for Faraday and the others, today's harvest can be regarded as a rewarding experience.

Then Faraday led the crowd to the operating table, ready to pack up the equipment and call it a day—Kirchhoff bought two fish earlier, and the remaining one was just right for lunch.

Xu Yun, Mai Riemann and others made an atmosphere group in the morning, and naturally they were very sensible and wanted to come up to help.

Mai and Riemann were responsible for packing the coils, while Xu Yun handled the vases and negatives.

But just when Xu Yun just picked up the vase.

Suddenly there was a voice in his ear that made his heart tremble:

"Ah, this is also weird."
